Answer: You're right - no plant is deer-proof - but arborvitae are not usually favored by deer and they are pretty much ignored. However, if the deer population is large and there is competition for food, a hungry deer will eat almost anything. Typically they browse the same path. Once they've tasted your arborvitae they will remember it wasn't necessarily a treat and they will probably nibble something much tastier in your garden, or in that of your neighbors. There simply are not any guarantees as far as plant desireability goes - it really depends on the deer population. If it's any help, spruces are not on the top of the list for deer munching, either, but a hungry deer might nibble them, as well. Wish I had better news for you!
